Saccharides with identical functional groups but with different spatial configurations have different chemical and biological properties. Stereochemisty is the study of the arrangement For example, galacturonic acid has the same configuration as galactose, and the structure of glucuronic acid corresponds to glucose.

Lactose has a molecular structure consisting of galactose and glucose. It is of interest because it is associated with lactose intolerance which is the intestinal distress caused by Hydrolysis is a chemical reaction in which water is used to break long polysaccharide chains into smaller chains or into simple carbohydrates.

Glucose + galactose = lactose, or milk sugar. The chemical structure of galactose is a bit different than glucose. On C-4 of galactose, the –OH is in the “up” position. On C-1 of galactose, the –OH is also in the “up” or position.

It is produced from the chemical decomposition of starch, which occurs during the germination of seeds and the production of alcohol. Lactose is a combination of glucose and galactose. Mucilages and gums are similar in structure. Mucilages are dietary fibers that contain galactose, manose, and other monosaccharides;

The structure of glycogen is similar to that of amylopectin, although the branches in glycogen tend to be shorter and more frequent. Glucose, galactose, and fructose are "single" sugars or monosaccharides. Two monosaccharides can be linked together to form a "double" sugar or disaccharide.

Major Types Of; Chemical Compounds; In Plants & Animals Lactose is a disaccharide composed of the two monosacharride sugars glucose and galactose. The following table shows the structure of a typical plant fat molecule (triglyceride) composed of glycerol plus 3 fatty acids. Since it contains unsaturated fatty acids,

It has a chemical structure similar to coumarin. Psoralen has been used in the treatment of certain cancers, including T-cell lymphomas in AIDS patients. Another potentially valuable herbal Upon hydrolysis saponin glycosides yield a triterpene or steroid sapogenin and one or more sugars, such as glucose, galactose,
